Odaily星球日报讯 Bitcoin mining ecosystem is rapidly developing, with significant progress in the use of clean energy. According to data from Woocharts, the proportion of clean or sustainable energy used in mining currently stands at 56.76%. Since April 2021, the usage of clean energy for BTC has been steadily increasing. The platform measures its clean energy usage based on the definition of sustainability from the Cambridge Centre for Alternative Finance, with relevant metrics depending on the share of energy sources such as wind, solar, hydro, and even nuclear in cryptocurrency mining operations. In recent years, Bitcoin mining companies like Riot Platforms and MARA Holdings have increased their investments in clean energy. However, against the backdrop of the current global energy crisis, mining costs continue to rise. To cope with this situation, most mining companies are utilizing their remaining capital to purchase Bitcoin.
